Natchswing asks: "My university has been given a $757,825 NSF grant to build, 'A 256 node (128 pair) Beowulf parallel computing cluster ... to improve the realism of gravity-wave modeling by permitting treatment of the three dimensional problem and multiple wave interactions.' They want to pay a company to just show up and drop off a functional cluster rather than build it themselves. Since word has leaked out regarding the purchase intent, every computer manufacturer under the sun (including Apollo himself) has called up trying to sell their cluster. Since I'm no cluster expert, I'm writing Slashdot. If you had $0.7 mil to buy a pre-built cluster who would you go with and why?"

avjewe asks: "I have a wireless (802.11) network in my 100 year old house. The walls are thick plaster, with enough metal in them to block the signal quite effectively. The floors, however, pass the signal just fine. Does anyone have any experience or suggestions as to how one can propagate a signal through a maze of faraday cages? I recently added an omni-directional antenna which, as one would expect, boosted the signal where I already had one, but didn't help the dead spots."

gManZboy writes "Bob Supnik, former team lead for DEC's VAX microprossesor, has an article up on Queue about his Computer History Simulation Project and how emulating old servers may be a better way to keep them running that servicing the physical machines. So how many PDP-11's can you run on a Pentium 4 anyhow?"

A snippet from the Wired story linked there: "Mobile warriors having trouble making a wireless connection across the hall might want to give some Ohio teens a call. This weekend they were able to make a 55-mile Wi-Fi connection. ... They might have achieved an even greater distance, Justin Rigling said, "but there was no road left."" (Here's the post from a few weeks back about the competition.)

SteamyMobile writes "As the article says, 'In a sign the Linux operating system may be gaining traction beyond server and other back-room systems, HP said Tuesday it will be the first major PC maker to ship a business notebook computer pre-installed' with Linux. This is great news because, as anyone who has ever tried to run Linux (or even Windows XP) on a laptop knows, laptops come with all kinds of funky hardware, and it's often a mess trying to find and configure the right kernel modules to make things like software suspend work correctly. Having it shipped pre-loaded, and with support, makes it easy for me to decide where I'm getting my next laptop. Linux has been ready for the desktop for a while now, but it is good to see companies like HP acknowledging that."

Yi Ding asks: "Recently, I have been investigating laptops for clients, and the majority of the complaints about current laptops is battery life. Most laptops just don't have enough juice to even finish a single DVD or write an article for 4-5 hours in an internet cafe. Of course, one can lug around extra battery packs, but it's a pain and often defeats the purpose of having a laptop in the first place, portability. What have your experiences with battery life been and where can I find the longest lasting, reasonably robust, laptop?"

Anonymous Coward writes "With all the press RFID is getting, I was looking for an open source solution to Wal-Mart's RFID compliancy mandate. I stumbled open the RadioActive project. I think these guys have the right idea. Eventually, RFID will be everywhere. Could an open source project like this bring rapid deployment of RFID like Apache did to the net?"

Saud Hakim writes "Intel showed a prototype of an IEEE 802.11a wireless LAN transceiver created by using a 90-nm CMOS (Complementary Metal-Oxide Semiconductor) fabrication. The chip can switch between different networks and frequencies; it is capable of tuning and tweaking itself. It is also capable of detecting what kinds of wireless networks are available nearby and shifting to the frequency that is most appropriate." Reader serox sends more: "Intel has two big news releases today and IntelFanboy has it covered. First up is the new Xeon processors have been released with a list of improvements. Second, Intel has revealed two significant milestones in the development of extreme-ultraviolet (EUV) lithography that will help lead to developing the next generation chip technology."

lokedhs writes "Sun Microsystems is coming out with new chips without connectors. According to the article, this will have a lot of advantages: 'Performance, for instance, could greatly escalate because the speed of transferring data among chips and the number of channels for the transfers would increase. Energy consumption could also decline. Just as important, overall costs could fall, because defective chips could be removed like Scrabble tiles.' This technology will also lead to new CPU's without cache: 'The technique could also allow designers to remove the cache--the large pool of memory currently found on the processor--and put it on a separate chip. Caches were integrated onto processors to amplify bandwidth. Adding cache, however, bumps up manufacturing costs, as it greatly increases the number of transistors. With the bandwidth constraint gone, caches could once again be made independent without it having an impact on performance.'"

Cloudscape, a small footprint Java database, is primarily used for small scale websites and point-of-sale systems. Its new, opensource name will be 'Derby.' Cloudscape (originally created by Informix, and purchased by IBM in 2001) has been valued by IBM at $85M."

Mr_KnowItAll writes "Our friends at DARPA have released the proposed rules for the 2005 Grand Challenge. They learned their lesson from the first one, now they will expect teams to submit a video demonstration of their vehicle's ability to complete the course before being invited to participate. Good, but they're also advancing the timeline to the point that it will be very hard to any team to start now and hope to participate. After all the fuss at DARPA's last-minute rule changes in '04, it's interesting to see that they're offering the proposed rules for community review and feedback."

Tarantolato writes "According to an eweek story Sun Microsystems will be debuting a Linux port of their Sun Ray Server at Linux World this week. This would allow Sun Ray thin clients to be run off of a SuSE or Red Hat box, where you previously needed a Solaris-SPARC setup to do that."

guroove asks: "I have a small gigabit ethernet network at home, and I spent a lot of money getting gigabit NICs for all my computers and even bought cat 6 cabling. I only have 3 computers on the gigabit network (a Mac, a Windoze machine, and a Linux box) so instead of getting a switch, I triple NIC'd the Linux box, which I use as a gateway and a file server. After the network was complete, I wasn't satisfied with transfer rates, so I started a transfer of a very large file and found that the transfer rate was topping off at just over 145 Mbps (which is a far cry from 1000 Mbps). I'm wondering now where my bottleneck is. Is it the NICs? Are all gigabit NICs really giving us 1000 megabits per second? Is it the driver? Is it Samba? Could it be that the hard drives aren't fast enough? Does anyone have experience with gigabit home networking enough to know where the bottlenecks are? Does the current PCI technology even allow for bandwidth that high"

Joel McShiston asks: "Back in Europe I had set up a system through which urgent emails matching certain criteria were automatically forwarded upon arrival to a (free) email account which my cell phone carrier (Vodafone) provided for free with each account - {cell number}@vodafone.es. At the carrier's site I could then turn 'SMS notification of new email' on and would receive a text message telling me to check my email each time a matching email came through. I'll be soon moving to the US and would like to know whether any of you has a similar (or better) system working over there. Which kind of SMS-email 'interfacing' are you able to do on that side of the pond?"

An anonymous reader writes "The race is on for first mover in the domestic US Linux smartphone market! Last week, Motorola announced a new Linux-based business user smartphone that's expected to ship to US customers by the end of 2004. Meanwhile, Chinese phone maker e28 will debut its latest Linux-based smartphone at LinuxWorld this week, and will soon begin distributing it in the Chicago area. Both devices are pretty cool. The quad-band Moto phone features a 1.3 megapixel camera, Intel's latest cell-phone chip, and fancy sync software that (currently only) works with Microsoft email servers at this point (others pending). e28's phone is an upgrade to its previously announced e2800, which became the world's first commercially available Linux phone when it shipped in China in August, 2003 [Slashdot discussion]. Interestingly, e28 was founded in 2002 by the former president of Mot's Asia Pacific cell phone division -- the world's largest mobile market."

It was still possible to retrieve photos from the xD and Smartmedia cards while the others didn't survive just the last two tests. "

vincecate writes "Recently AMD updated their processor roadmap. It shows their move to 90 nm and has a range of new processors over the next 1.5 years, including dual-core chips. An unofficial AMD roadmap shows speeds and performance increasing. Intel also recently updated their roadmap. Intel does not show anything faster than the current 3.6 Ghz in the next 11 months, including the recently delayed 4 Ghz chip, except to say '3.6 Ghz or greater.' Strangely, some of the recent SPEC benchmark results show the 3.6 Ghz chip to be slower than the 3.4 Ghz chip. One possible explanation for this is that the 3.6 Ghz chips will slow down due to 'thermal throttling' if you are not very careful to keep them cool. So it seems like heat may be the reason Intel's roadmap does now show much improvement."
